As I mentioned in my previous post about Raspberry Pi power monitoring, I recently built a VMware vSphere “datacenter” from three Intel NUC mini PC’s. One limit of the NUC is that it has just one Ethernet port. But there’s a Mini PCIe slot inside the fourth-generation NUC that can be used to add a second Ethernet NIC!
NUT is a wonderful and extensible power management framework, and the Raspberry Pi is an awesome platform on which to run the UPS monitoring drivers and upsd server daemon. Even if you’re not running vSphere, a Pi running NUT makes sense for the connected servers found everywhere today.
